JOHN HOUGHTON CLARKE, OF FRAMINGI-IAM, MASSACHUSETTS.

SCRAPER.

SPECIFICATION forming part of Letters Patent No. 688,160, dated December3, 1901.

Application filed June 15, 1899- T0 ctZZ whom, it may concern.-

Be it known that I, JOHN I-IoUeHToN CLARKE, a citizen of the UnitedStates, and a resident of Framingham, county of Middlesex, and State ofMassachusetts, have invented certain new and useful Improvements inScrapers, of which the following is a specification, reference being hadto the accompanying drawings, forming a part thereof, in which similarcharacters of reference indicate corresponding parts.

My invention relates to an improved combined ice-chisel, scraper, andshovel attachment forbrooms and handles; and its object is to provide asimple, durable, inexpensive, and efficient device of this class adaptedto be attached to a broom-handle to be employed as a means for removingice or other incrusted substance from sidewalks, doorsteps, da o.

The invention will be hereinafter described, and particularly pointedout in the claim.

In the accompanying drawings, forming a part of this specification,Figure 1 is a plan of a blank employed to produce my improved device.Fig. 2 is a front elevation of the device in a finished state. Fig. 3 isa side elevation thereof, showing the same attached to the end of abroom handle. Fig. 4 is a sectional plan View taken on the line X X ofFig. 3, and Fig. 5 is a rear elevation showing the device connected to abroom.

The scraper is formed from a single piece of sheet metal, preferablysteel, and stamped or cut into shape substantially like the blankillustrated in Fig. 1 of the drawings,consistin g of the blade portion 1and the socket portion 2, the latter being provided with apertures 3 forthe reception of screws used in fastening the device to a suitablehandle. The blank is provided with the shoulders 5 and is cutdivergingly from the inner corners of the same to a point 5 at the outeredges of the blade, leaving a straight perpendicular lower edge 7. Whenthese diverging edges 6 and a portion of the straight edge 7 are bentupwardly, they form triangular strengthening flanges C, (shown in Figs.2 and 3,) and the broadest portion of the flange being between the point5 and that part of the blade where the greatest strain is brought tobear, thus giving theblade more strength and rigidity at that part.

The two side edges 7 of the Serial No. 720,657. (No model.)

blade are parallel andextend at right angles to the cutting edge 19. Inbending the flanges C only a portion of the edge 7 is turned upwardly toa point 8, as shown in Fig. 2, thus leaving a wide flat projectingchisel or cut ting edge which is free of flanges at its ends, so as topermit the edge I) to be freely sharpened and the free use of the deviceas a chisel in cutting or chopping. After the socket has been formed thedevice may be secured to a broom or other handle by two screws D, whichengage the openings 3 in the socket and screw into the materialcomprising the handle.

My invention involves a scraper struck up or otherwise formed of asingle piece of sheet metal and comprises the socket to fit on asuitable handle, the wide fiat sharp chisel end without side flanges orprojections, and the shovel portion extending from the socket to saidchisel end and arranged at an angle to the length of the socket and alsoat an angle to the plane of said chisel end. Said shovel portion tapersin width from the said chisel end to the socket, and the side flanges ofthe shovel portion taper down to and terminate at the junction betweenthe shovel portion and chisel end. The angle of inclination of theshovel portion is such as to bring the flat chisel end in the plane ofthe length of the socket, as shown by Fig. 3, whereby the side flangesare highest and of greatest strength at the portion of the scrapersubjected to the greatest strain, and the chisel end is located in thedirect line of strain with the handle to which the scraper is attached.By reason of the peculiar structure and arrangement as described myscraper can be easily struck up from comparatively thin sheet metal andis of great strength and durability, and by reason of the peculiarstructure of the shovel portion in relation to the plane projectingchisel end it can be employed as an ice-chisel to chop and break upthick ice and frozen snow on pavements, steps, &c., as well as a scraperfor cleaning off thin ice and snow and throwing the same to one side.

I am aware thatscrapers embodying a blade and an integrally-formedsocket are not new. I therefore do not claim the broad idea; but I doclaim the specific structure as herein shown and described, embodying anexceedin gly durable device which will stand considerable strain withoutliability of bending or breaking the blade.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s

A scraper formed from a single blank and composed of the socket toreceive a handle, the shovel portion extending from one end of thesocket and longitudinally inclined,

and the planeflat chisel end I), projecting from the shovel portion andarranged in a plane including the central longitudinal axis of saidsocket, said shovel portion formed
